<p num="1"><br/><br/><br/><br/> A method of estimating loss of <br/>a splice between first and second optical fibers <br/>spliced together by a mechanical splice or a <br/>mechanical splice-based connector having a <br/>portion through which light leaked from the splice <br/>can emerge comprises the steps of launching light <br/>into the first fiber, collecting light leaked from the <br/>portion using a multiplicity of ports, measuring <br/>the power level of the collected light and deriving <br/>the insertion loss from the measured power level, <br/>a predetermined power level and a collection factor <br/>C representing a relationship between measured <br/>power level, predetermined power level, power <br/>level of light in the first fiber, and power level <br/>of light coupled into the second fiber previously <br/>obtained for the same or similar connecting device. <br/>The ports may be angularly spaced about the axis <br/>of the connector or splice. The predetermined <br/>power level may be obtained by measuring light emerging from the connector but <br/>without the second fiber in position.<br/>
